           if err := json.NewEncoder(w).Encode(respObj); err != nil { 
        
           	log.Printf("json enc: %+v", err) 
        
           } 
        
           // set header 
        
           w.Header().Set("Content-Type", "application/json;charset=UTF-8") 
        
           // set cors header 
        
           corsHeader(r, w)

When json.NewEncoder(w).Encode(respObj) is executed, set cors header
will never be executed. Therefore, it cann't be implemented across requests.We should put set header before json Encode.

	// set header
	w.Header().Set("Content-Type", "application/json;charset=UTF-8")
	// set cors header
	corsHeader(r, w)
